Abstract

Comutatorul telefonic cu senzor, conform inventiei, este un dispozitiv electronic care realizeaza comutarea a doua sau mai multe posturi telefonice cu linie comuna spre centrala telefonica, înlocuind comutatoarele mecanice cunoscute. Comutatorul telefonic cu senzor este compus dintr-un etaj de alimentare-redresare, un etaj electronic cu senzori, un etaj de semnaizare si un etaj de comutare a posturilor telefonice. Alimentarea comutatorului telefonic cu senzor se poate face atât de la retea, cât si de la o baterie de acumulatori de 12 V, tensiunea fiind folosita si pentru semnalizarea optica si sonora a postului telefonic chemat. în etajul de semnalizare este închisa o lampa care indica pozitia releelor în repaus, cât si confirmarea legaturii pe linie atunci când s-a realizat. Comutarea liniei de la un post telefonic la altul se face prin atingerea cu degetul a celor doi senzori.The sensor switch according to the invention is an electronic device which switches two or more common line telephone lines to the telephone exchange, replacing known mechanical switches. The sensor switch consists of a power-up stage, an electronics floor with sensors, a sign floor, and a switching stage for the telephone stations. Power supply of the telephone switch with sensor can be done both from the network and from a battery of 12 V batteries, the voltage being used also for the optical and sound signaling of the called station. a lamp indicating the position of the relays at rest is closed in the signaling stage and a link on the line is confirmed when done. Switching the line from one phone to another is done by touching the two sensors.
